Still no Viera Link though.
After reading every written word relating to RIHD/Viera Link/CEC/HDMI Control/connection problems, I have finally solved my RIHD/Viera Link problem!
The standard remedies are:
Turn it off and on again.
Turn it off for 15 minutes and on again.
Switch RIHD and Viera Link on and off.
Reset TV and/or AVR to factory settings. (and lose Audyssey settings
All possible combinations of the above.
None of this sorted out my HD control. It had worked before, so I decided to go right back to the beginning and unplug EVERYTHING, all HD cables, ethernet, all but the speaker cables (so not quite everything).
Before powering off I turned Viera Link on the TV and RIHD on the AVR OFF, and then powered off both devices for about 20 minutes.
Then turned on the link stuff and plugged things in one at a time (it worked with just the TV!) and as some of you might expect, the SKY+ HD box was the culprit! I know the Sky CEC problems are quite well known due to their non standard use of pin 13. Some of you might also be saying why didn't I just start with that, but I had! I had tried unplugging the Sky cable and resetting but it still didn't work.
Some people also said back in 2010 that this issue had been solved.
Once finding out that it was in fact Sky, I did some more tests. The Onkyo justs needs a sniff of the Sky HD cable and its HDMI control is stuffed. No matter what I did the link was unavailable until unplugging everything again, turning off for a while, and starting from scratch. There was no coming back from a 'broken' link due to Sky.
I had also in the past tried the Sky HD straight to the TV, but due to the cable being in the vicinity of the Onkyo prior to trying this, the connection was already out for the count so whatever I tried wasn't going to work.
So now I have the Onkyo plugged into the ARC port (HDMI 2) and Sky in HDMI 1 and power and volume are working as expected with RIHD/Viera Link!
The only downside I can think of with this setup is Sky HD now bypasses the Onkyo meaning no upscaling from 1080i to 1080p. Another small downside is having to change the TV input source to access the Onkyo on screen menu, but this is hardly an issue.
A better solution (I think), which some have done, is to remove pin 13 from the HDMI cable for the Sky box. I didn't do this, but now that I'm fairly sure I know the issue I might do that. It would mean everything going into the Onkyo and one cable to the TV, thus fully maximising the audio and video processing potential of this awesome AVR!
Something to point out; even though the Sky box is connected to the Onkyo with an Optical cable to get 5.1, when ARC kicks in and the receiver switches to TV/CD the default audio is the ARC source (i.e. 2 channel for Sky), which also needs updating to Optical. I guess this makes sense, but due to my original setup with Sky -> Onkyo, I had set the SAT audio source to Optical so didn't think of needing to also update the ARC source at first.
Apple TV goes into the Onkyo and doesn't effect the HDMI control at all. (as expected from Apple...)
After solving the Viera Link problem I needed to redo Audyssey, and after reading the very informative and useful link
in jdsmoothie's signature on Audyssey setup, I used all 8 measurement points this time (instead of 3 like at first) and my setup has really come to life! Have never heard it sound this good! Another useful tip in that post is not to decrease the Audyssey crossover frequencies (increasing is ok). Yes this is probably obvious to some of you, but a lot of stuff you read also says go with the THX recommended 80Hz. I am now leaving my KEF's on the 120Hz suggested by Audyssey.
A final point: this is untested, as I didn't want to have to redo the whole unplug/reset/wait/plug in thing again, but there is a small chance an HDMI -> mini display port cable (like this
) also messes with CEC control, even when NOT plugged in to anything! I had a cable plugged in but not connected to my Macbook but it still might have also been involved in my troubles. Whatever goes on in the little box thing connected to the HDMI side might be tying pin 13 to another pin or something, I don't know.
I hope this is of some use to someone out there! Thanks to all who offered suggestions.
